Indepth training

[assasen11]

I am looking for courses and in depth training on some of the features of Opnsense I don't understand fully. Is there anything I could find online or pay for for this? I know I could pay 400 some dollars for four hours of support but I just want to understand the software a little better so that I can support my implementation of the software. Any ideas?

Thank you in advance.
